Claims

[Scope of utility model registration request]

A core for a solenoid having a fuel passage formed therein, a magnetic plunger having a passage aligned with the passage and disposed at the tip of the core via a non-magnetic annular sheet so as to be moved toward and away from the tip with a minute stroke, and the plunger. a valve body provided at the tip of the valve body, a valve seat member formed with a valve seat that forms a valve together with the valve body, and a nozzle that is provided on the valve seat member and opens and closes with the movement of the plunger by the valve body. An electromagnetic fuel injection device, characterized in that the valve seat member is elastically supported to reduce impact when the valve body is seated on the valve seat.
